[Given]
{ x + y = 6
{ x = y + 4
[Plug-in our x value & solve]
[Given] x + y = 6
[ Plug-in] (y + 4) + y = 6
[Distribute] y + 4 + y = 6
[Combine like terms] 2y + 4 = 6
[Subtract 4 from both sides] 2y = 2
[Divide both sides by 2] y = 1
[Answer]
Third option - (5, 1)
-> You do not need to solve for x since this is the only option that has y = 1, but to solve for x we would do y + 4 = 1 + 4 = 5, so this answer fully checks correctly

Answer: 12
Step-by-step explanation:
6c + 11= 2c + 59
Collect like terms
6c - 2c = 59 - 11
4c = 48
c = 48/4
c = 12
Answer:
{ -4,-2,0,2,4}
Step-by-step explanation:
The range of the inverse is the domain of the function
The domain of the function is the x values
Domain{ -4,-2,0,2,4}
This is also the range of the inverse
The ratio between the bigger triangle and the smaller triangle is 1:2, which means the smaller triangle is half the size of the bigger triangle.
You simply need to half all the values of the segments of the bigger triangle to find the values of the segments of the smaller triangle.
8/2 = x; 4 = x
6/2 = y; 3 = y
